Salaam,
@Saeed,
According to SWT FAQ <http://www.eclipse.org/swt/faq.php#missingdll>, from
version 3.3, there is no need to put these native files in PATH, as they
already exist in jar file. Are you sure you didn't unpack jar file? You
should have swt-mozilla-gtk-3800.so in swt.jar (which should itself exist in
<zekr>/lib folder).
